@Marvin can I create a task from a class instead of a function?

Based on the search results, here's how you can define a task using a class in Prefect 2.x: In Prefect, tasks are typically defined using the

@task

decorator on functions. However, you can also use a class to define tasks by leveraging the decorator within your class method. The Prefect documentation doesn't provide an explicit example for class-based tasks, but you can achieve this by defining methods within a class and decorating them with

@task

. Here's an illustrative example:

python
from prefect import task, flow

class MyClass:
    def __init__(self, message):
        self.message = message

    @task
    def show_message(self):
        print(self.message)

@flow
def my_flow():
    instance = MyClass("Hello from the class!")
    instance.show_message()  # Decorated method is a task

if __name__ == "__main__":
    my_flow()

In this example: 1. We defined a class

MyClass

with an

__init__

method and a

show_message

method. 2. The

show_message

method is decorated with

@task

, making it a Prefect task. 3. Within the

my_flow

function, we create an instance of

MyClass

and call the

show_message

task. So, yes, you can create tasks from a class by decorating the methods and using them in your flow. For more detailed information, you may refer to the Prefect Tasks documentation. If you have more questions or need further assistance, don't hesitate to ask!
